    This update for emacs fixes the following issue:

    - CVE-2026-96442: arbitrary code execution when viewing or editing untrusted text files in modes other     than Emacs Lisp       mode (bsc#1282390).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote SUSE Linux SLES16 / SLES_SAP16 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2026:23949-1 advisory.

    This update for emacs fixes the following issue:

    - CVE-2026-96442: arbitrary code execution when viewing or editing untrusted text files in modes other     than Emacs Lisp       mode (bsc#1282390).

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A code execution flaw was found in Emacs, affecting versions prior to 31.2. The Flymake mode using     language backends other than Lisp would execute arbitrary code from the edited file while performing     syntax checking. Viewing or editing untrusted files using Emacs could lead to arbitrary code execution     with the privileges of the user running Emacs. (CVE-2026-96442)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Oracle Linux 9 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2026-85245 advisory.

    - Generalize trusted-content-p check to all Flymake backends (CVE-2026-96442)

The remote Redhat Enterprise Linux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:84591 advisory.

    GNU Emacs is a powerful, customizable, self-documenting text editor. It provides special code editing     features, a scripting language (elisp), and the capability to read e-mail and news.

    Security Fix(es):

    * emacs: GNU Emacs: Heap over-read leading to information disclosure via crafted image (CVE-2026-77219)

    * emacs: emacs: Command injection via crafted filenames in TRAMP (CVE-2026-79992)

    * emacs: Emacs: arbitrary code execution in Flymake mode (CVE-2026-96442)
